Answer=B
36 red marbles
64 blue marbles
red marbles:blue marbles
36:64
now lets simplify the ratio by dividing both numbers by 2
18:32
continue simplifying by dividing both sides by 2 again...
9:16
The ratio of red to blue marbles is 9:16

Standard form:

Since the exponent of the scientific notation is negative −14, move the decimal point 14 places to the left. 0.00000000000006359.
Answer: 
Step-by-step explanation:
The complete exercise is: "The circumference of a circle is 47.1 and the diameter of the circle is 15. Which best represents the value of π? "
In order to solve this exercise, it is important to remember that the circle can be calculated with the following formulas:
1. 
Where "C" is the circumference of the circle and "D" is the diameter of the circle.
2. 
Where "C" is the circumference of the circle and "r" is the radius of the circle (Remeber that the diameter is twice the radius).
In this case, the exercise gives you the circumference of the circle and its diameter. These are:

Then, knowing those values, you can substitute them s into the first equation
, as following:

The final step is to solve for
